4 T0 all whom 'it may conern:

' a simple mechanism in an adding and listing machine by which theamount may be printed and at the same operation deducted from the amountpreviously registered on 'the accumulator wheels. This end is attainedby having each numeral key set two inde- 'pendent stops for limiting thetravel of the actuators when operated, one set of stops being incorrespondence with the numbers on the keys and which limit Athe travelof the actuators. andsset the .printing type in accordance with thenumbers on the keys depressed and the other set of stops being such asto limit the travel of the actuators after a movement equal to thecomplement of the numbers on the keys depressed, and a selective devicebyfwhich the actuators may be made to engage either set of stops at thewillof the operator so that the machine will add the number set' on thekeyboard when engagingy one set of stops and add the complement of thenumber set up on the keyboard when engaging thel other set of stops, thetype for printing the amount being regulated in its position-'in eithercase by the first set of stops. This mechanism is shown and illustratedin connection `With the machine known as the Ellis adding-typewriter,.which is fully .set forth ings in whichin detail in my British PatentNo. 28253 of Dec. 28, 1908. f

A detailed follows, reference beingA-had to the draw- Figure 1. is alongitudinal vertical section with parts in the normal position of rest.Fig. 2 is a similar section to parts just at the vvposition forreleasing the printing sectors.'r Fig. 3. is a view of the.

subtracting key showing'its immediate connecting devices. Fig. 4. is afront view of the keyboard 'showing the` lateral arrangenient of theparts and also a frontJ view ofA Athe subtracting key and itsconnectingmechanism. Fig. is a detailed view Aof ther Specification of Letterslatent.

vdescription of the. device is as Fig. 1. with the A.piece R53. 6. is adetailed view of the tend to` raise the keys K3". These stops K23 andK2* extend through the order plate 60K. Mounted on the order plate K isran irregularpiece K, mountedto ,slide horizontally on studs 181219K. Theupper side or edge ofthe piece K71 is arranged with a series of stepsfor engaging the stops K2* whenA in their depressed position and thesesteps are arranged Vernier fashion so that ther eX- treme righthand onein the drawing will move a distance of one pitch or tooth of theactuator rack before engaging the stop KM. The second step will move adistance Y of vtwo pitches or teeth and the laststep a distance of ninepitches or teeth. The function of the piece K71 will be more fully eX-plained in connection with other mechanism.w

The actuators of the adding wheels A33 consist of the sliding racks-R30having teeth on their upper and lower edge for engaging two sets ofaccumulatorsand are made to. slide over the bar R33 at the rear end andover the bar K3 at .the forward end. The

rack R30 has no direct means for engaging thel stops K23 and I 3*. Itsform is shown 1n Fig. 6. Parallel with the rack R30 and sliding over thesame bars R32 and K3 is another sliding piece R33, shown in detail inFig. 5. This piece R33 has a series of `steps at its forward endarranged Vernier Jfashion to `engage the stop pins K23 when the same aredepressed. The first 'step on thepiece R33 engages the stop I 23 on thefirst key'on the keyboard and permits the piece R33 to Patented Apr. 2o,1915. Application led October 3, 1912. Seria No. 723,756. I y

move tothe'rear of themachine a distance t equal to one'pitchor'tooth'ofthe. rack R3".

The second stepengages the stop pin K23 on the second keystem K59 andpermitsA the piece R33 to move a distance of two teeth of the rack -R3,etc., each step permitting the slide R53v to move one tooth fartherthanthe preceding one 'in a rearward direction.

'This sliding piece,R53 also carries a slot on its lower edge forengaging the plece Rullo which operates the crank lever R211 whichswings on the shaft R1 and through the connecting rod P53 controls thesetting ofthe type sectors P54. The restoring bar RA is in' the form ofa bail and is secured to tLhe shaft" R1 and swings from the positionshown in Fig. 1. to the position in Fig. 2. carryingwith it'the vbarR12, and spring R80 extending from vthe bar. R51 to a verticallyproject-- ing horn on the rack R5o and when R45 is in the position shownin Fig. 2. the spring R80 tends to move the rack R50 to the rear of themachine. Mounted on .the crank lever R is the alining sector RT2 and thespring R21 extending from the bar R51 to the pin at the forward end ofthe alinjing sector R52 [tends to swing the crank lever R45 inthe samedirection as the restoring bar 4512 and by means of pin R14 engagingtheslot in the lower side of the slidingpieceR53 tends to move R53 in arearward direction.

Referring to Fig. G Jzhere will be seen the piece R58 of irregular shapewhich is pivoted on the sliding rack R50 and va small spring R22 tendsto'keep the pieceR?a in its lowered position. Thepiece R56 has a rackcuton its upper -side at fthe forward end and a small lip on its lower side for-engaging the vpin R1'7A in the sliding piece R52.

Mounted on the'pivot 18K' is a segment` -raekK22 having an upwardlyextending arm carrying a1V pin 20K whichengages a vertical slot in thepiece. K73

to the piece' Kn. v 1 Y A mall arm R" is securedftc a sleeve R21 whichis free to turn upon the shaftfl?. The

A forward end of the piecelt56 pivoted to R'S0 rests on the upperend ofythe small arm R57' and :R57 can assume either of two. positionsthatshown in Fig. 1. and that shown in Fig.'

Fig. 1. and the position shown in Fig. 2. be-

- ing the position yassumed when the subtract# H endwhich pressure 1sdue to the spring R22.

The mechanism for causing the piece R51 to assume the'position shown inFig;2. is shown .in Fig. 3. 7012 vis the vsubtractimgg-key the lower'endof which is supported by the bracket 711K "secured to the underside ofthe keyboard and the spring Ksttends to hold the Vkeystem .70K 'in itselevatedv position.

This lkey K is made in the usual -form em-vv ployed inthis machine forthe operation 60 keys such as totalvand subtotal keys,and is providedwith a' notch et on its rear edge. The latch rpiece 72K is pivoted ltothe 'sidel frame Bu'at 'K22 and has a lip 12"for`engaging the notch a.in' the'keystem 70K. A pin 15Kv in the lower end of the )latch 7221engages a slot in the upper end of the piecel which in issecured.

the-left and the arm R57 moves from theV position shown in Fig.. 1. tothe position shown in Fig. 2. and is retained in thisposition until.tlie machinel performs its complete cycle of operations which aredetermined by the rotation of the shaft O1 through an angle of aboutsixty degrees and its return to its normal position. vThe speed ofrotation of this shaft O1 is regulated by the govemol- D42 (see Fig. 3.)and the arm 51D is swung from the position shown in Fig. 3. to aposition about vertical in the direction indicated by the arrow and onthe return str o'ke the trigger 55D pivoted on the end of the arm 51Dengages the turned over lip c of, the piece 72K and restores thepece`72K- tothefposition shown in Fig. 3. thereby releasing .the key 70K,disengaging the lip b from the notch a and also restores the piece74Kfto its normal position'and incidentally' the arms R57 `to theposition shown vin-Fignl. L The pin D12 serves to disengage the trigger551` from the lip c on thepiece '72K leaving the piece 72K free tolengage the key 70Kv when the same is again depressed. The engagement.of the trigger 55D with the lip a'on thel piece 72K .is caused by thespring D25 -maintaining'the trigger 55D in a position to engage the lipc while the trigger 55D `is making its upward stroke.

In describing the operation of this device I willjfirst consider therelative position of the parts when the machine is to perform vvthefunction of addition. VThe key 70K being `in its elevated position thearm R57 will `beinia lowered position as shown vin Fig. 1. and he pieceRSS-pivoted to the rack R5 -fwill engage by means of the small lip onits lower' side the pnfR17 with a consequence that-when the restoringbar 4511 is moved in a rearwarddirection `the rack R20' and the piece-R58 will move solidly together as one piece and the travel or movementof these two pieces will be determined by the'extent of travel permittedthe piece R52 by the stops K23 and; all functions and movements of themachine will be in all respects similar to a regular adding machine ofthis type. The type sector P54 will move in unison with the slidingpieces R53 and-the rack R5. A complete description ofthese operations isfound in my British Patent No. 28253 of Dec. 28, o 1908. v

To cause the machine to subtract, first de press the amount to besubtracted on the keys K2" of the keyboard; next the key IOKV v.isdepressed 'and the mechanism Shown in.

Fig. 3.'causes the arms R51 to raise the piece Ri the teeth on the'upperedge thereof engageLthe teeth of the segment K12 `and the small lip onthe lower Side of R" disengages the pin R in the piece R03.' Whenthercstoring bar 45R moves to the position shown vin Fig. 2. the spring R80will move the piece v R00 to the rear until the steps on the upper sideof the piece R53 come in contact with the stops K on the ykeys K09 whichare 'depressed and the piece R03 will cause the type sector P54 topresent a type for printing lthat vwill correspond` to the depressed keyK.

At .the same time the spring RfL will move the rack R to the rear; thepiece R5 being` secured'thereto and its teeth in engagement with thesegment K'I2 will turn rK72 and through the pi'n20K move the slide K71in a forward direction until one of its steps engage the -stop K2* onthe depressed key K0'.

.The distance from the center of the pivot 18K to the teeth onthesegment K72 being the same as the distance from Vthe center of thepivot 18K to the pin 20K the distance traveled by the rack R50 andthesliding piece K'I1 will be the same but in opposite directions,- andthesteps ,on the piece K11 are arranged ver- Anier fashion so that whenthe nine keyK59 is depressed the piece K71 willmove a distance equal toone tooth of the rack R50; the

piece K71 always moving a distance equal in -until its third step.engages the depressed stop I 24 on the keystem K5".

In a machine of this type each column of ke'ys acts in exactly the sameway, and its mechanism is a duplicate inv all respects of each of ltheother columns with the exception of the column at the extreme righthandside, commonly known as the unit colo umn. In the drawing in Fig. l. andFig. 2,

the mechanism of the Vrst orlunit column is shown. This column ,ofkeysK59 must present for operation a series ofstops K2* to limit thetravel of the rack R00 after a movement equal to the complement inten ofthe number on the depressed key K0, but in all other columns it mustbeto the complement in 9 and this difference is accom# plished bysecuring the small piece Kn*I farther to the rear on K71 by a distanceequal to one tooth of the rack R00 that while the depression of theseven key K50 inthe righthand column causes the rack R00 to move adistance of threeteeth, the depression of the seven key in all othercolumns will only cause the rack R00 to move a distanceof two teeth. Ifno key K00 is depressed and the machine is-operated with the subtractionkey K-down, the rack R50 in the righthand col- Dec. 28, 1908.

umn will move a distance of ten teeth, to allow which movement a smallextra space (Fig. l.) is removed from the underside of the rack R00 atthe front end. Alll of the other racks R50 will move to the rear a.distance yofnine teeth, but the pieces RV will not move at all andconsequently nothin'g will be printed, the type sectors P5* remaining,in their normal position.

The mechanism and v'means to rcausethe different parts of this devicetoA function properly in performing theact f addition andthe printing ofnumbers are fully set forth in my British Patent No. 28253 of In orderto maintain the piecesl K71 and K"2 in their pro er position forengagement with piece 00, it is'nece'ssary to lock them, while themachine is in use for purpose of addition, and a lock K is provided,

which engages a small notch on the lower side of the piece K, andtheother end of the piece K restsagainst the upper end of the piece R",sothat when the piece R7 is moved to the position shown in Fig. 2, it

disengages the lock K" from the piece K01.
